Patent JP-H08101707-A (JP)
Title: Unit and method for numerical control
Inventor: SAKAGUCHI YOSHIFUMI
IPC: G05B19/4155
Filed: 1994-09-30
Abstract: PURPOSE: To shorten a machining time while maintaining positioning precision. CONSTITUTION: A movement command outputted from an interpolation arithmetic part 20 is inputted to servocontrol parts 41 and 42 in advance and then the movement quantity of a mount base can be estimated before the actual response. Then an in-position decision part 70 calculates the quantity of position deviation at an end point position from the estimated movement quantity and the movement end point position of the mount base outputted from the interpolation arithmetic part 20, and outputs a machining start signal when the position deviation quantity is less than a previously set permissible value.

Title: Input circuit
Inventor: HOSHI TOSHIAKI
IPC: H03K17/30
Filed: 1992-09-04
Abstract: PURPOSE:To provide an input circuit which can automatically control the input logical threshold value within a prescribed range despite the change of the environmental temperature and also can satisfy the outside specifications concerning an input level equivalent to the conventional level even under the strict conditions of an assured temperature range. CONSTITUTION:A series transistor TR circuit consisting of the PMOS TR P3 and P4, P5 and P6, and P7 and P8 is set in parallel to a PMOS TR P1 which constructs a CMOS inverter circuit. A comparator 12 compares the self- oscillation frequency of a ring oscillator 15 with the frequency of a clock signal CLK serving as the standard for the frequency inputted from the outside via the counters 14 and 13. Thus the difference of both frequencies is detected. Then the result of this detection is inputted to a selection signal control circuit 11, and the levels of the signals C1, C2 and C3 which turn off the PMOS TR P4, P6 and P8 respectively are controlled based on the difference of frequencies. Then the ratio of current ability calculated between the CMOS and NMOS TRs of the CMOS inverter circuit is changed and the input logical threshold value is automatically controlled in response to the temperature change.

Title: Chain conveyor
Inventor: NAGURA NARIYUKI
IPC: B65G17/24
Filed: 1992-09-04
Abstract: PURPOSE:To provide a chain conveyor where a part or a plural number of portions of a line can be increased in speed by providing an accelerating means which can freely press/separate a horizontal pusher plate to/from the lower surface of rollers from below, below the rollers at least, in a part of the range of a feed chain line. CONSTITUTION:When a chain 14 is driven in a state that a carried article is rested thereon, the rolling of a carrier roller 21 over a chain rail permits the carrier roller to be moved together with a chain 14 while a roller 20 is being supported, so that the roller 20 feeds the carried article. When the roller 20 is moved on an accelerating means 26, and if a pusher plate 24 of the accelerating means 26 is pushed upward by an air cylinder means, the roller 20 is rollingly brought into contact with the upper surface of the pusher plate 24. Therefore, the roller 20 is brought into contact with the chain rail so as to be pulled up by the chain 14, so that the roller is thereby rotated by itself. This constitution thereby allows the circumferential speed of the roller 20 due to rotation by itself to be applied to the carried article in addition to the moving speed of the chain 14, so that the carried article is accelerated in speed to a great extent so as to be carried on.
